I bought these to hold different concentrations of ink wash. They do what I need them to do, and they don't spill, but sometimes when I open them the ink inside splashes out everywhere because of the tops.

Love to use these cups for pastel colors I have to shave off my pastel pencils and my hard pastels to get a sharp point for painting. They are large enough that I can shave directly in the cup and yet store many in a small space.

We manufacture accessories for musical instruments and use these for our #1 seller. It sets them apart from the competition and makes for a useful and valued solution. The consistent quality and fast service will bring us back year after year.

I bought these to use for my screen printing enamels that I'm using to silk screen onto glass. The 2" size are perfect for the amount of enamel I need to silk screen the half a dozen prints I usually do at a time. The lids fit quite tightly, so I don't have to worry about the enamel drying out if I didn't use all of it up at one time. Just what I needed!

I am an artist "and" a scientist. In my biological laboratory we've found these containers to be very useful in preserving and containing insects and plant material. The seal is strong and the plastic is 100% clear! Very easy to see colors through and specimens.

I also use these in preserving paint when I mix for animation cels. Never had paint dry out. I can't say anything bad! Great product!
